From 1cf903851279309b9060357ce73e1ed680757929 Mon Sep 17 00:00:00 2001 From: Andrew Bartlett Date: Mon, 3 Mar 2003 09:12:40 +0000 Subject: Fixes to the vfs_fake_perms modules - we only need to specify the VFS functions that we actually modify. Also a better implementation of the stat() and fstat() functions.
